The magnitude of resistance $X$ in the circuit shown below in the figure, when no current flows through the $5Ω$ resistor, is

Options:

Answer:

Solution:

As no current flows through the middle $5Ω$ resistor, the circuit represents a balanced Wheatstone bridge. $∴ \frac{X}{18} = \frac{2}{6}$ or $X = \frac{2}{6} \times 18 = 6Ω$
